The DS4 first stage lacks the rotating turret found on the XTX50 first stage and offers one HP port. This compact first stage is a time-proven workhorse that has been embraced by the technical community around the world.
- Four medium-pressure ports all mounted on a rotating turret resulting optimal hose routing while eliminating sharp bends in the hose.
- The first stage is over-balanced resulting in a higher medium pressure at each depth.
- Left /right reversibility providing multiple regulator configurations.
- Features the innovative Diver Changeable Exhaust (DCE) System allowing the diver to change from a large exhaust tee to a smaller exhaust tee.
- The larger and smaller exhaust tees both are included with the regulator.
- Using the venturi control lever, the diver can prevent unwanted free flow when the regulator is out of the mouth and achieve a venturi boost while diving.
- Easy-to-grip opening effort control knob.
- Suitable for cold water use.
- Compatible to EAN 40 new, out of the box.
